Answer:
A. The lytic lifecycle allows viruses to reproduce more quickly but also kills the host and forces the virus to find a new host cell.
Explanation:
The lytic lifestyle of the viruses (e.g. bacteriophage) can be described through the next steps:
- attachment and injection into the host cell (e.g.bacterial cell)
- synthesis of the early virus proteins which break down host's DNA
- virus uses host's machinery (for the replication, transcription and translation) to produce the rest of its proteins and to form new virus particles.
- host cell burst and many new virus particles are released.
During the lysogenic cycle, virus does not kill the host. It integrated its DNA into host's genome and stays dormant until conditions are optimal for reproduction.
The air you breathe into your lungs on a daily basis mostly consist of carbon dioxide.
D) all of the above are potential disadvantage for the use of adult stem cells.

Answer:
